Hi,


Since the fan is not running and no lights in the front, you most likely have a bad power supply.

Since you don't have a service contract, you maybe able to find a used  power supply on ebay and replace it.  I have never opened up a 3550, and not sure is this is even doable.  You may want to check your 3550 before buying another PSU.

as reza mentioned your PS might be dead. Look around ebay and you will find many...if its too expensive then throw that switch away and buy another one on ebay


sometimes its easy to buy annother one than fix the old one

  You can either buy a different switch , or  attempt to replace the power supply .  This switch has been EOL for a few years now so cisco wont replace it .
